+1 on ferrits. On Feb 28, 2012, at 22:23, Joe Fiero joe1...@optonline.net wrote: Tim, I have had 100% success by using a good quality shielded cable and following a strict bonding regiment. Bonding the antenna, radio, mast and cable to the tower at the top is imperative, as is the same process at the bottom. It's also important that the tower be bonded and that the bond is common with that in the equipment room. Make sure the inside end of the cable is bonded as well. In other words, there should be no difference in potential between the ground in the equipment room, the tower or your equipment on the tower. You must carry that bonding through to the rack and equipment you place in the room as well. Also, be sure to use grounded cable on jumpers. And the real trick is putting ferrite beads on both ends of the POE cable. I had a site exhibiting between 50 and 70 percent packet loss between the topside radio and the router in the room when initially installed. The installer never noticed there were two FM stations on the tower ( 55Kw and 30Kw ). We even swapped radio equipment twice because he insisted there were no transmitters in close proximity. Once we discovered the FM stations he did as I described above and we went immediately to 0% packet loss from the router.

Finally I installed ferrite beads on both ends of all cat 5 runs. Things are running pretty well now. Turns out that cat5 and fm radio are basically in the same frequency area. My best advice?

Re: [WISPA] ethernet and towers with FM transmitters
Something I've heard talked about in ham/engineering circles is don't have cable runs that are near a half wavelength or multiple half wavelengths of the frequency that's giving you trouble. It's a last ditch effort but it might be worth thinking about. Ferrites are great. When you put them along the cable again avoid half wave length intervals. You want to do everything to discourage the cable from resonating at the interfering frequency. Greg On Feb 29, 2012, at 12:31 PM, Marlon K. Schafer (509-982-2181) wrote: This problem is a bitch.

Re: [WISPA] transparent caching solution w/TPROXY
I'll check out those other caching solutions. I was going through the ryohnosuke.com website, it's in Spanish (Via google translate). The main company referred me to him to coordinate since he speaks English. To get it setup in the Mikrotik it took a couple of mangle prerouting rules and a route with a routing mark. It actually just routes the traffic to the cache instead of redirect, this keeps the transparency working nicely. If I disable the mangle rules then nothing goes through the cache. In Mikrotik I imagine you just use mangle to add routing marks to port 80 traffic then add routes based on those marks. Do websites accessed see the IP of the cache or IP of the user behind the cache? Can you munge your mangle and routing rules and post them? ___ Wireless mailing list Wireless@wispa.org http://lists.wispa.org/mailman/listinfo/wireless
Re: [WISPA] Excede (viasat-1) Satalitte Internet
It still has exceedingly bad latency just like any other satellite service, but the capacity figures are true (at least until those spot beams become more saturated) Also watch out for the bandwidth caps, and contract terms. I'm not sure I would use Skype or Vonage on a service like that.

Re: [WISPA] Excede (viasat-1) Satalitte Internet
I'm not familiar with them but that service has got to have bandwidth caps like DirecWay. Also it's hard to believe that Skype and Vonage would work well because they must be over-sold (high contention ratio) at that price.
